WisDOT_DTSD_BTO_STOC_511 XML - Archived Data Management Subsystem Functionality

Subsystem Description

The Archived Data Management Subsystem collects, archives, manages, and distributes data generated from ITS sources for use in transportation administration, policy evaluation, safety, planning, performance monitoring, program assessment, operations, and research applications. The data received is formatted and tagged with attributes that define the data source, conditions under which it was collected, data transformations, and other information (i.e. meta data) necessary to interpret the data. The subsystem can fuse ITS generated data with data from non-ITS sources and other archives to generate information products utilizing data from multiple functional areas, modes, and jurisdictions. The subsystem prepares data products that can serve as inputs to federal, state, and local data reporting systems. This subsystem may be implemented in many different ways. It may reside within an operational center and provide focused access to a particular agency's data archives. Alternatively, it may operate as a distinct center that collects data from multiple agencies and sources and provides a general data warehouse service for a region.

Advanced data analysis and mining features to support discovery of information, patterns, and correlations in large ITS archives.

Functional Area: Traffic and Roadside Data Archival

Collects and archives traffic and environmental information directly from the roadside for use in off-line planning, research, and analysis.
